Uneven Dream: locations API returns null

[zebraed]

Descriptions

/api/gamelocations returns null for uneven dream, causing locations button to not appear in front side

Root Cause

• unevendream has multiple protagonists, so wikiwrapper API requires protag parameter for multi-protagonist games
• updateLocationCache() in server/locations.go doesn't pass protag parameter

[zebraed]

and, requires corresponding ynoproject/wikiwrapper update to include protag field in API responses
this change should be made to improve on the forest-orb side
